Dr Shan Lou is a Senior Research Fellow with the Surface Metrology Group (SMG) of the Centre for Precision Technologies (CPT) and ERSRC Future Metrology Hub. He is currently carrying out research work in the field of precision metrology.
Shan received his BEng and MEng at the Central South University in China. He started his professional career in precision metrology at Hexagon Metrology, a leading global company in the metrology industry. Shan then moved to the University of Huddersfield to pursue a PhD degree whilst working for Hexagon Metrology on a part-time basis.
Shan is an editorial board member of the journal 'Bio-design and manufacturing', a Committee Member of the British Standard Institution (BSI) AMT/8 (Additive manufacturing) and TDW/4/4/1 (XCT), an International Scientific Committee member of the European Society for Precision Engineering and Nanotechnology (euspen), a Chartered Engineer of the Institution of Mechanical Engineers (IMechE), and a Fellow of the Higher Education Academy (HEA).
Shan was recently awarded an EPSRC New Investigator Grant and an RCUK Catapult Researchers in Residence Grant. Working with the National Measurement Institute (NPL), the Catapult HVM centres (MTC, AMRC, A*Star ARTC), and wide industrial partners (Digital Surf, Nikon metrology, HiETA), he is investigating precision metrology technology for the additive manufacturing industry. 
Shan is the peer reviewer for many engineering and scientific journals, including Measurement Science and Technology, Measurement, Precision Engineering, Surface Topography: Metrology and Properties, IEEE Transactions on Instrumentation & Measurement, Optical Express. He was also an organising committee member and a session chair of ASPE Summer Topic Meeting – Advancing Precision in Additive Manufacturing, an organising committee member of the 4th Dimensional X-ray Computed Tomography conference.
Apart from research, Shan has been involved in teaching: (1) Lecture of NFA2168 Mechanical Engineering and Science; (2) Lecture of NFE2105 Engineering Mathematics; (3) Supervision of final year projects; (4) Supervision of Master by Taught summer projects.
